Unlike the national unemployment figures, the metro data aren't adjusted for seasonal factors, such as the layoff of temporary retail employees after the winter holidays. That can make the data volatile from month to month.

The jobless rate fell in 70 of Oklahoma's 77 counties, while the rates were unchanged in five counties and higher in two, the state Employment Security Commission said.

The lowest county jobless rates were out west, with a 2.2 percent rate in Roger Mills County and 2.4 percent in Ellis County.

The highest unemployment rates were in southeastern Oklahoma, where Le Flore County's 9.7 percent rate was the state's worst. Sequoyah County had a 9.3 percent jobless rate, followed by McCurtain County at 8.9 percent.
